Description jens 2010-04-11 10:17:25 UTC

Version:            (using KDE 4.4.2)
Compiler:          gcc4 Standaard Ubuntu Lucid
OS:                Linux
Installed from:    Compiled From Sources

When watching a video with the Plasma Media Player Widget I see inverted colors, like completely wrong hue/saturation settings. Dragon player shows the colors just fine with default video setting.

I'm using the gstreamer phonon backend. I see this issue in my own compiled KDE4.4.2 version and also in a VirtualBox openSuse machine with KDE 4.4.2 (factory).

I can still see this behaivor on two completely updated systems (opensuse 11.3, kde4.4; ubuntu 10.10, kde 4.5) with update gstreamer,xorg and nvidia drivers. Where exactly upstream should this bug have been fixed?

"Where exactly upstream should this bug have been fixed?"

regardless of where, this doesn't make it our bug and therefore a reason to re-open the report.

it's an issue with phonon/gstreamer -> qgraphicsview.

I sincerely apologize for reopening the report. Since it said "resolved->upstream" I thought this bug got resolved somewhere else (eg. gstreamer) and I just have to wait for the next distribution update for getting newer versions of the base system. I didn't read it as "This is not a KDE problem, please look somewhere else" (i fact if I had known that, I would have tried to contact the phonon folks a half year ago :( )

Regards, Jens

PS: Thanks a lot for your work on KDE, regardless the miscommunication, I really appriciate what you are doing here.

I think that this is more a bug of a backend, when we reparent previously embedded widget to normal QWidget then it still has wrong colors (it is easier and much more reliable to reparent widget than keep more than one and reconnect them...).
Also this worked fine with Xine backend (rarely worked at all but if worked then worked fine).

Was this issue reported upstream anyway?

I don't know about other, but I haven't reported this one anywhere besides here since I don't know exactly where the issue comes from. 

Regards,
Jens

I've asked about this bug on IRC and it seems to be backend bug fixed in changeset 0907004e.

Very cool, looking forward to the next phonon-gstreamer version. Thanks for your info on this!
